About your PSA result

Information about prostate-specific antigen (PSA) test results to detect prostate cancer. PSA is a protein made in the prostate gland. As men get older and the prostate gland grows larger, they may produce higher levels of PSA. However, higher levels of PSA can also be caused by other conditions. One of these is prostate cancer. An elevated PSA level means something is happening in the prostate gland, and further investigation may be required.
